Hallwyl Castle
Aargau
Hallwyl Castle is one of Switzerland's most important moated castles, situated on two islands in the River Aabach near Lake Hallwil in the canton of Aargau. Founded in the late 12th century, it was originally the residence of the noble Hallwyl family who controlled the surrounding lands and lake. The castle developed from a residential tower with a dry moat into a fortified water castle with a curtain wall and multiple buildings on artificial islands. It suffered damage during the Swiss Confederation's conquest of Aargau in 1415 but was promptly rebuilt and expanded. Notable architectural features include the residential towers, the keep with the Verliesturm tower, and the castle mill on a third island. The castle underwent neo-Gothic renovations in the 19th century, later reversed to restore its medieval character. Since 1925, Hallwyl Castle has been open to the public, and since 1994 it has been owned by the canton of Aargau as part of the Museum Aargau. Today, visitors can explore its historic halls, exhibition spaces, and the surrounding natural reserve, experiencing a unique blend of medieval fortification and residential elegance.

History
Hallwyl Castle was first mentioned in 1256, with origins traced back to the late 12th century when the Hallwyl noble family established a residential tower surrounded by a dry moat.
In the early 14th century, the castle was expanded into a moated water castle with two islands and defensive walls.
It was partially destroyed by Bernese troops in 1415 during the conquest of Aargau but was rebuilt and extended in the following decades.
The castle evolved into a representative late Gothic residence between the late 15th and 16th centuries, with additions such as turrets and a grand hall.
After periods of neglect and neo-Gothic renovations in the 19th century, the castle was restored to its medieval state in the early 20th century.
In 1925, it was opened to the public and later transferred to the canton of Aargau in 1994, which undertook comprehensive renovations.
